Nature of Business	Nature of Business PASSUR Aerospace, Inc. (“PASSUR” or the “Company”), a New York corporation founded in 1967, is a leading business intelligence company, providing predictive analytics and decision support technology for the aviation industry primarily to improve the operational performance and cash flow of airlines, airports, fixed based operators (FBOs) and air navigation service providers (ANSPs). The Company provides a cloud-based platform, ARiVA™, that manages and optimizes operations for its customers. PASSUR uses big data, within the aviation intelligence platform and a suite of web-based solutions that address the aviation industry’s intractable and costly challenges, including, but not limited to, the underutilization of airspace and airport capacity, delays, cancellations, and diversions. PASSUR’s mission is to improve global air traffic efficiencies by connecting the world’s aviation professionals onto a single aviation intelligence platform, making PASSUR an element in addressing the aviation industry’s system-wide inefficiencies. It is an aviation intelligence company that makes air travel more predictable, gate-to-gate, by using predictive analytics to mitigate constraints for airlines, airports and their customers. PASSUR delivers digital solutions that are essential to global aviation operations, meeting the needs of global air travel as well as supporting the recovery of the aviation industry from the COVID-19 crisis. The structure and execution of operations within the aviation industry has fundamentally changed as a result of this crisis due to the significant change in the economics required to support current conditions, a return to normal operations and profitability. PASSUR continues to be a pioneer applying artificial intelligence powered by machine learning to aviation data, addressing the industry’s most costly challenges, including the management and optimization of airspace, airport assets, aircraft, and day of flight operations. PASSUR’s information solutions are used by airlines and airports in the United States as well as in Latin America. PASSUR provides data aggregation and consolidation, information, decision support, predictive analytics, collaborative solutions, and professional services. Solutions offered by PASSUR help to ensure flight completion, covering the entire flight life cycle, from gate to gate, and result in reductions in overall costs and carbon emissions, while helping to maximize revenue opportunities, as well as improving operational efficiency and enhancing the passenger experience. PASSUR’s commercial solutions give aviation operators the ability to optimize performance in today’s air traffic management system, while also achieving Next Generation Air Transportation System (“NextGen”) and Single European Sky ATM Research objectives. PASSUR integrates data from multiple sources. Certain of PASSUR’s services traditionally relied on its proprietary network of sensors for aircraft surveillance. During the second quarter of fiscal year 2020, in light of the FAA's mandate for ADS-B equipage on aircrafts operating in most U.S. airspace, effective January 2020, and parallel adoption of ADS-B requirements in much of the world, the Company performed a comprehensive review of its data feeds, specifically those associated with the PASSUR Network units, and external ADS-B data feeds to determine if these external data feeds provide sufficient redundant data as to that generated from the existing PASSUR installations. The Company determined that such services could be powered by a combination of FAA data plus commercial ADS-B aggregator feeds and other data feeds available to the Company, which would provide a more cost-effective solution and allow the Company to focus more on value-added analytics, and less on sensor technology. In this regard, the Company reviewed and decommissioned approximately half of its PASSUR Network system assets during the second quarter of fiscal year 2020. As a result, the Company wrote off the total net book value of the net assets applicable to the PASSUR Network systems of approximately $3,565,000, and lease assets applicable to these PASSUR locations of approximately $175,000 during the second quarter of fiscal 2020, which amounts are included in the impairment charge for the year ended October 31, 2020. The write-off amount included PASSUR System and SMLAT System assets as well as inventory of finished and spare parts. The Company essentially completed the decommissioning process during fiscal year 2021.
